PEDAL.

SPECIFICATION forming part of Letters Patent N o. 618,424, dated January31, 1899.

Application filed October 18, 1897. Serial No. 655,603. (No model.)

is a specification.

My invention relates to an improvement in pedals; and my object is toprovide a pedal possessing extreme simplicity of parts,readily takenapart or put together, and having bearings Which are practicallydust-proof. Incidentally the cost of manufacturing the pedal is lessenedmaterially, and the pedal is lightened in structure and enhanced inappearance.

I accomplish my purpose by making the pedal sleeve or barrel removablefrom the pedal-frame along with the pedal-crank pin, the ball-bearingbeing entirely Within the sleeve and removable With it. Such anarrangement besides contributing to the dustproof feature of the pedalalso provides for the easy and nice adjustment of the ballbearing. Otherpoints of advantage Will be suggested by the description which follows.In the accompanying drawings, Figure l represents a development of theperipheral band or foot-bearing portion of the pedalframe. Fig. 2 is abroken sectional View of the pedal and crank-pin Figs. 3 and ,views inelevation of the inner and outer crosspieces, respectively, of thepedal-frame; Fig. 5, an inner end View, on a reduced scale, of the pedalbarrel or sleeve; and Fig. 6, a longitudinal sectional View of the same.

A is a stamped band or frame-blank provided in the stamping operationwith perforations t i and s s', which serve as sockets forcross-piecesBand C. (Shown in Figs. 3 and 4, respectively.) Thecross-pieces are provided at the ends With studs r r' and q q',respectively, Which fit into the sockets mentioned after the frame-blankhas been bent to shape, and by means of these studs the cross-pieces areriveted in place. The cross-piece B is provided centrally with anoutwardly-turned ringor flange B', stamped-integral With it andinternally threaded, as shown, and the cross-piece C isprovidedvcentrally with an outwardly-extending cup-shaped depression Cof somewhat smaller diameter than the ring B and stamped integral withthe crosspiece.

Fitting into the cross-pieces is a pedal sleeve or barrel D, having itsinner end (the end toward the Wheel) provided With a head D', havingWrench-engaging surfaces, as shown. The barrel D being comparativelyshort and therefore of comparatively small cost I prefer to make itentirely of steel, providing it at the inner-end with a hardenedball-bearing surface p and toward the outer end With anintegrally-formed interior cone n. The sleeve D receives a crank-pin E,which is provided at one end with a ball-bearing surface m and has itsopposite end reduced in cross-section and provided with al thread l,said reduced portion being adapted to receive a threaded cone k, awasher 7c', and a nut k2. The outer end of the barrel D may be made tofit so snugly into the cup C as to exclude dust effectually, the bottomof the depression serving as a dust-excluding cap Which protects andcloses the outer end of the barrel. y The cavity Which receives .theouter end of the barrel may be characterized, therefore, as a bottomeddepression as distinguished from an uncovered perforation. The onlyportion at all open to exposure is Where the crank-pin E contacts at thering E With which it is supplied With the enlarged end of the barrel,and this is in a position Where it may be supplied readily With adust-cap, though I have shown none in the drawings.

The greatest advantages of my pedal lie, as I have pointed out, in theextreme simplicity of its parts, the readiness with Which they may beassembled, and the easy and nice adj ustment of the ball-bearing.

Suppose it is desired to clean or adjust the bearing. It is necessaryonly to place a Wrench upon the head D of the barrel D, When the lattercan be readily separated from the pedal. This leaves the nut k2 exposed,and by means of the iingers or of a Wrench adapted to iit into the outerend of the barrel this nut can be removed, and after that the cone Zocanbe removed or adjusted at will.

While I consider the construction shown and described best adapted to mypurpose, yet 'I do not Wish to be understood as in any IOO senselimiting myself to speciiic details,except as shall appear from theappended claims.

What I claim as new, and desire to secure by Letters Patent, is-

1. A velocipede-pedal comprising a frame having cross-pieces, a sleeveremovably secured to said cross-pieces, a crank-pin removably andadjustably secured within the sleeve and ball-bearings between thesleeve and crank-pin, and independent of the frame, whereby the latteris detached without dismembermentA and without disturbing the bearings,substantially as described.

2. A velocipede-pedal comprising a frame having an inner cross-pieceprovided with an integral bottomed depression, and an outer cross-pieceprovided with a threaded opening, a sleeve one end of which occupies thedepression, and the other end of which is threaded to engage J[heopening, a crank-pinV in the sleeve, ball-bearings between the sleeveand crank-pin and independent of the frame, and means vfor adjusting thebearings accessible after the detachment of the frame, substantially asdescribed.

3. The combination of a pedal-frame provided with pedal-sleeve supports,an integrally-formed readily-removable pedal-sleeve extending throughthe inner one of said supports with which it has screw connection andhaving its inner end enlarged and provided interiorly with aball-bearing surface and its outer end provided with an interiorball-bearing surface, a crank-pin in said sleeve provided with aball-bearing surface m and a reduced and threaded outer end portion, anda cone having screw connection with said reduced end portion,substantially as and for the purpose set forth.
